20.8.10 Quick stop
Deceleration to a stop is executed with the Quick stop command of Control word 1 (PROFIdrive standard)
and Controlword (CiA 402 standard) (P24640). The servo motor decelerates to a stop according to a time
constant of Quick stop deceleration (P24709) and the state shifts to Switch on inhibited (Switch on disabled).
The state shifts to Switch on inhibited (Switch on disabled) and the motor stops with the dynamic brake for tq.
The following shows related PROFIdrive parameters.

Refer to table 8.10 for details.
The operation method of deceleration to a stop can be specified with Quick stop option code (P24666). The
following table shows the supported methods and the operations. Basic operation is the same as the forced
stop function. The difference should be only the deceleration time constant.

tq: The state shifts immediately to Switch on inhibited and the motor stops with dynamic brake.
pp/pv: The servo motor decelerates to a stop with Profile deceleration (P24708) and the state shifts to Switch on inhibited
(Switch on disabled).
hm: The servo motor decelerates to a stop with Homing acceleration (P24730) and the state shifts to Switch on inhibited
(Switch on disabled).
(Not compatible) (Note)
2
pp/pv/hm/pt/jg/idx: The servo motor decelerates to a stop with Quick stop deceleration (P24709) and the state shifts to
Switch on inhibited (Switch on disabled).
tq: The state shifts immediately to the Switch on inhibited and the motor stops with dynamic brake.

The current is limited and the motor decelerates. Then, the state shifts to Switch on inhibited (Switch on disabled). (Not
compatible) (Note)
4
The voltage is limited and the motor decelerates. Then, the state shifts to Switch on inhibited (Switch on disabled). (Not
compatible) (Note)
5
The motor decelerates to a stop. Then, the state does not change from the Quick Stop Active (servo-on). (not compatible)
(Note)
6
The motor decelerates to a stop with Quick stop deceleration (P24709). Then, the state does not change from the Quick
Stop Active (servo-on). (not compatible) (Note)
7
The current is limited and the motor decelerates. Then, the state does not change from the Quick Stop Active (servo-on).
